For Father's Day, we decided to tell Daddy that we love him in Sidewalk chalk. My husband really likes words of affirmation to let him know he is loved. So the Friday before Father's Day, we went out and decorated the driveway to tell him why we loved him. It was something all three children could do...even if the one year old kept trying to eat dirt...
I wrote "We [heart] you Daddy!" and the kids decorated around it. Brayden made a stop sign so cars would know to not run over the writing.
Daddy loved it! This is something you can do during nice weather months. You could even go to a home of a neighbor and tell them how great they are in sidewalk chalk (but you might want to be pretty sure your neighbor won't mind).
Sidewalk chalk is always fun, but it seemed to be extra fun with a goal in mind.
